So after a few thousand miles on the Pulsar and doing the update, MDS is now disabled. Whenever I put it in drive, the gear indicator simply goes to manual mode automatically. I do like the device and wish it had more options at this price point. I drove around in performance for a while but the gas pedal sensitivity was so much, I didn't like to drive that way in traffic. I then drove around for several thousand miles at tow tune. This was prob my fave but gas mileage dropped about 2 miles per gallon. I then drove around in stock, yup pretty much stock. I'm on 35"s with stock gears and economy gauge sits at 13.6 after most tanks. I have not programmed for tire size. Economy makes the gas pedal feel like a limp noodle. Got to push the heck out of it to go anywhere, didn't like that.
I always fill up with mid grade. I have towed 10k a number of time and do believe the tow tune has a little seat of the pants improvement. When you change performance levels it seems like it takes a few drives for the transmission to relearn and give an acceptable shift pattern. It might hang in gear a bit or downshift early till it relearns.
Overall I'm happy? I think? I guess? I'm not gonna to take it off but look forward to what options we get in the future.
